/*
 * @name Shape Primitives
 * @description The basic shape primitive functions are triangle(), 
 * rect(), quad(), ellipse(), and arc(). Squares are made with rect() 
 * and circles are made with ellipse(). Each of these functions requires 
 * a number of parameters to determine the shape's position and size.
